Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Installed ubuntu but grub doesn't show my old windows install as an option

I have 3 SATA drives with 2 in raid0 which contains the windows7 installation I'm interested in, and the 3rd holding two versions of ubuntu (I think, I've lost track). There is also an IDE drive with windows xp.

Messing with BIOS settings I can select either the IDE drive or the raid0 to boot from. When I boot from the IDE I see the old ubuntu and windows xp in grub. When I boot from the raid0 I see two versions of ubuntu and windows xp but no windows7!

Here is the results of a boot info script someone suggested running...

Grub 2 is a disaster still, because it is so new... I'v spend daze wrestling with it, before I said enuff is enuff.. until they progress more. The docs are scant, and other information scattered over the net is either wrong, too complicated, or otherwise misleading.

The quick fix would be to trash it, put the old reliable grub (legacy)ver 0.97-61 back on.

The only thing to consider extra, because you have ext4 (I think on all your partitions).. is to put your /boot (ie. grub files, kernels, initrds, etc.) on a small separate ext3 partition, or grub (legacy) won't be able to read them.

Neither Grub Legacy nor Grub2 actually boot windows but simply point to the windows bootloader which then takes over. Your script output shows Grub2 in the mbr of sda and sdd and xp boot files in sdc.

xp by default is not capable of booting win 7. win 7 can boot xp. If you review your script output, you will see entries for xp in the grub.cfg file but none for win 7 which is the opposite of the way it should be with the windows bootloader capabilities.

I'm not familiar with Grub2 as it is still beta.
You will probably need to figure out some way to get win7 to boot xp and I expect you can search support.microsoft.com for an answer. Don't use either myself. I'm not sure what impact raid setup will have?
